Hey everyone, over the last year I noticed corraline growing on my back wall. So I wanted to leave it alone and let it take over. I've noticed over the last 4 months a green algae has grown on top, or trying to compete.

Just want a perspective before or if I put a plan of action:

Scrape or DONT SCRAPE?

Don't scrape, get a Tang. Also, take a look at how much your feeding and your nitrate level....green stuff grows best when params are off.

No tangs for me. Only a 65G. Was dealing with low nutrients for a while (1-2 nitrates and 0 phos) now my nitrates like 20 lol.

The coralline does not look healthy. There are patches where it looks eaten or flaked off. The green algae is growing on it probably because of its poor health.

How'd you get them up, just more feeding or are you dosing
I was going to dose but my hunch told me to try au natural. Literally fed reef roids every other day and upped fish feeding twice a day for a few weeks.

Well. I just tested. This is a no Brainer

Dkh 6.7 <--- salifert
Mg 1320 <--- salifert
Ca 455 <--- red sea
Nitrate 5 <--- aqua forest
Phos - 0 <---- use salifert...im gonna need a Hanna for this one.

Gotta stay on top of the dosing for sure.

So NO to scaping off the green algae on the wall?

I would leave it and let nature do it’s thing. Use it as a guide to see how your husbandry is going. Just my opinion.

Sorry no clue, but I see in your latest post you might have found a possible cause.

Just a thought, now that algae has a foothold on the dead coralline, adding PO4 might make a mess on the glass.

Doing the almost exact thing. Been feeding roids everyday to raise Po4.

Now I also have some green growing on the back wall of tank covering up the coralline.

My plan, cut back on the roids and do a light scub on the alga. Coralline will grow back.

Ya. I'd rather have a lil green than Dinos or cyano anyway tho. So you'd scrape it huh?

Not scrape. Going to lightly scrub with a magnet float. At least I’m hoping to save most of the coralline that way. If I pull the magnet part off then a light scrub might do it.

I’m going to do it later today. I’ll let you know how it goes.

Agree with you there!!

That'd be awesome!! Throw in some pics. I usually like to do a bi-yearly large water change....I think I'm due for one. But...I also don't want to strip all the nutrients out. But it's been about 6 months since I've done that (30%day 1 30% 2 days after and 30% 2 days after that).

I run my 65G tank on a cannister filter with no skimmer lol have to keep on top of husbandry. But has worked well for me thus far.

Unless things get out of control I don't like to dose my tank. I did have a GHA outbreak that I couldn't control, so I did give a very conservative dose of vibrant (half of a half recommended dose). I read once you start to dose things you'll have to continuously do that.

Glad it worked for you tho!!!

some of the coralline flaked off but not much. Also used the mag float to scrub off some of the spirobid snails. The White dots are annoying sometimes.
